Note: Basophilic stippling is due to ribosomal inclusions in RBCs, while papenheimer bodies are iron deposits, Heinz bodies are precipitated hemoglobin seen with special stain (He for Heinz and He for Hemoglobin), and Howell Jolly bodies are DNA remnants
The aggregates are partially composed of Iron but visible with and without iron stain (as opposed to sideroblast's iron granules which are only visible with iron stain)
